From the Guidelines
Breastfeeding mothers with sinus infections can safely use antibiotics like amoxicillin, amoxicillin-clavulanate (Augmentin), or azithromycin, which pose minimal risk to nursing infants. According to the most recent study 1, oral amoxicillin/clavulanic acid is suggested for breastfeeding patients who require systemic antibiotics. The typical adult dose for amoxicillin is 500mg three times daily or 875mg twice daily for 5-7 days, while Augmentin is usually 875mg/125mg twice daily for the same duration.
Key Points to Consider
- These medications transfer into breast milk in very small amounts that are not harmful to most babies 1.
- Penicillin-allergic mothers can safely use azithromycin (500mg on day 1, then 250mg daily for 4 more days) or clindamycin (300mg three times daily for 7 days) 1.
- It's best to take antibiotics immediately after nursing to minimize the concentration in milk.
- While taking antibiotics, watch your baby for potential side effects like diarrhea, rash, or fussiness, though these are uncommon.
- Stay hydrated and continue breastfeeding regularly, as stopping could worsen your infection by causing milk stasis and potentially lead to mastitis.
Additional Considerations
- The risk of hypertrophic pyloric stenosis in infants exposed to macrolides during the first 13 days of breastfeeding is very low 1.
- Most systemic antibiotics will be present in breast milk, which could cause falsely negative cultures in febrile infants or produce gastroenteritis due to alteration of intestinal flora 1.
From the Research
Breastfeeding and Antibiotics for Sinus Infection
- The safety of breastfeeding while taking antibiotics for a sinus infection depends on the type of antibiotic used 2.
- Most antibiotics used to treat sinus infections are considered safe for breastfeeding mothers, but it's essential to consider the pharmacokinetic profile of each drug to ensure the resolution of the maternal infection and the safety of the infant 2.
Antibiotic Options for Sinus Infection
- Amoxicillin-clavulanate is a commonly recommended antibiotic for treating acute bacterial sinusitis in both children and adults 3, 4, 5.
- Cefdinir is another effective option for treating acute bacterial rhinosinusitis, with a once-daily dosing regimen and good respiratory tissue penetration 4, 6.
- Other alternatives include cefuroxime, cefpodoxime, or cefdinir, and in cases of serious drug allergy, clarithromycin or azithromycin may be prescribed 3.
Considerations for Breastfeeding Mothers
- When choosing an antibiotic for a breastfeeding mother with a sinus infection, it's crucial to select an option that is safe for the infant and effective against the causative pathogens 2.
- The American Academy of Pediatrics and other organizations provide guidelines for the use of antibiotics during breastfeeding, and healthcare professionals should consult these resources to make informed decisions 2.
